Rails 在 Heroku 上使用邮戳 API 的电子邮件 -- 连接由对等方重置
Rails email using Postmark API on Heroku -- connection reset by peer
我今天身上多处瘀伤,试图同时学习两件事...API 邮戳和 Rails HTTP 请求。
目标:使用 Postmark add-on 让 Heroku 发送生产电子邮件。
我正在尝试结合这篇关于 HTTP 请求的文章...
http://docs.ruby-lang.org/en/2.0.0/Net/HTTP.html
...使用此 API 邮戳参考...
http://developer.postmarkapp.com/developer-send-api.html
不幸的是,Postmark 中的示例是在 curl 中完成的,我没有成功将它们转换为 HTTP 请求。我怀疑问题集中在 headers -- 除了 body.
之外的传输部分
下面代码中的 rescue 子句捕获了错误 'connection reset by peer'。在这一点上,我不知道我是否接近提供邮戳身份验证的 headers 的正确格式。
我有正确的服务器令牌(在配置条目中)并且发件人电子邮件已获得所需的邮戳签名。
def send_production_email(email_address, subject, email_body)
# Use API to interact with Heroku add-on Postmark
# http://developer.postmarkapp.com/developer-send-api.html
uri = URI('https://api.postmarkapp.com/email')
# Form the request
req = Net::HTTP::Post.new(uri)
# Set request headers -- SUSPECT THIS IS WRONG
req['Accept'] = 'application/json'
req['Content-Type'] = 'application/json'
req['X-Postmark-Server-Token'] = Rails.application.config.postmark_token
rbody ={
'From' => 'Support <michael@mydomain.com>',
'To' => email_address,
'Subject' => subject,
'HtmlBody' => wrap_html(email_body),
'TextBody' => email_body
}.to_json
req.body = rbody
# Send the request, waiting for the response
begin
response = Net::HTTP.new(uri.host, uri.port).start {|http| http.request(req) }
rescue Exception => e
logthis("http request error: #{e.message}")
return
end
# ...parsing section omitted since I do not get that far...
end
第二次尝试以这种方式格式化,但导致相同的对等重置错误:
rbody ={
'From' => 'Support <michael@disambiguator.com>', # TODO: replace email when domain is live
'To' => email_address,
'Subject' => subject,
'HtmlBody' => wrap_html(email_body),
'TextBody' => email_body
}.to_json
uri = URI('https://api.postmarkapp.com/email')
http = Net::HTTP.new(uri.host, uri.port)
# http.use_ssl = true
request = Net::HTTP::Post.new(uri.path, {'Content-Type' => 'application/json', 'Accept' => 'application/json', 'X-Postmark-Server-Token' => Rails.application.config.postmark_token})
request.body = rbody
# Send the request, waiting for the response
begin
response = http.request(request)
rescue Exception => e
logthis("http request error: #{e.message}")
return
end
非常感谢您的指导!

"connection reset by peer" 错误是由于您尝试将未加密的 HTTP 请求发送到期望通过 HTTPS 进行安全通信的端点而导致的。因此,如果您更改此行:
Net::HTTP.new(uri.host, uri.port).start {|http| http.request(req) }
至:
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
response = http.start { |http| http.request(req) }
那么您应该能够收到来自 API 的回复。我看到你在第二个例子中有这一行,但它被评论了。既然你是作为练习来做的,我想补充一点,当使用 net/http
时,你通常不必使用底层的 classes,比如 Net::HTTP::Post
。使用 Net::HTTP
class 的实例提供的更高级别 API 通常更简单。以下是如何使用它简化您的方法的示例:
def send_production_email(email_address, subject, email_body)
uri = URI('https://api.postmarkapp.com/email')
http = Net::HTTP.new(uri.host, uri.port)
http.use_ssl = true
headers = {'Accept' => 'application/json',
'Content-Type' => 'application/json',
'X-Postmark-Server-Token' => Rails.application.config.postmark_token}
payload = {'From' => 'tema@wildbit.com',
'To' => email_address,
'Subject' => subject,
'HtmlBody' => email_body,
'TextBody' => email_body}
http.post(uri.request_uri, payload.to_json, headers)
rescue => e
puts "http request error: #{e.message}"
end
而且,如果您对如何在官方邮戳 Ruby gem 中使用 net/http
感兴趣,请查看 HttpClient class’ source。
